Patented Oct. 14, 1930 v UNITED STATES PATENT OFFICE DONALD S. BARROWS,OF ROCHESTER, NEW YORK, ASSIGNOR TO THE GOULD COUPLER COMPANY, OF DEPEW,NEW YORK, A CORPORATION OF MARYLAND SIDE FRAME Application filed April18,

This invention relates to side frames for railway trucks and moreparticularly to the reinforcement of the connection between the ends ofsuch frames and journal boxes formed integral therewith.

The principal object of my invention, generally considered, is thereinforcement of the union between integral journal boxes and theadjacent ends of cast side. frames for railway car trucks.

Another object of my invention is the strengthening of the junctionbetween integral journal boxes formed at the ends of side frames forrailway car trucks by reinforcing the lower web of the tension member ofsuch side frames and extending such reinforce ment beyond the junctionswith the journal boxes, and along the roofs thereof.

A further object of my invention is the rigidifying of the endconstruction of east side frames with integral journal boxes andparticularly of such side frames in which the tension and compressionmembers are generally U and inverted U-shape in cross section byproviding upstanding ribs extending approximately along the longitudinalcenter line of the web of the tension member and continued past thejunction with the journal boxes over the roofs of said boxes.

3.0 A still further object of my invention is to provide a specialreinforcement adjacent the junctions between inL-lgral journal boxes andthe ends of east side frames, said side frame preferably comprising atension member formed with a lower web and upstanding side flanges, saidweb being united with the jourmail boxes adjacent the upper corners ofthe inner brass lugs thereof, the junctions being reinforced byupstanding ribs preferably beaded alon their upper edges and taperinglongitudinally both ways from the junctions with the nai boxes aiong theweb of the tension rr the enter on is of said ribs preferably mergingwith ribs extending along the transverse center line of the boxes andconnecting the side walisof the frame, the junctions with said boxesbeing preferably additionally reinforced by beaded gussets between theinner r and the roofs of said boxes,

side Walls of the boxes and the underside of the tension member. 4

Referring to the drawings illustrating my invention, the scope whereofis defined by the appended claims:

Figure 1 is a plan of one end of cast side frame for railway car trucks,a portion there of being shown in section.

Figure 2 is a fragmentarv vertical longitudinal sectional view of theframe illustrated in Figure 1.

Figure 3 is a transverse sectional view on the line 3-3 of Figure 2,looking in the direction of the arrows.

Figure 4: is a sectional view corresponding 05 to Figure 2 but showing amodification.

Figure 5 is a transverse sectional view on the line 55 of Figure 4:,looking in the direction of the arrows.

Figure 6 is a sectional view corresponding to that on the line 66 ofFigure 4 but showing another modification.

Referring to the drawings in detail, like parts being designated by likereference characters and first considering the embodiment of myinvention illustrated in Figures 1, 2 and 3, there is shown one end of acast side frame 1 formed with a compression member 2, a tension member3, and integral journal boxes 4, only one of which is illustrated. Aswill be understood, the frame is symmetrical and is formed as usual withthe compression member and tension member extending substantially thefull length thereof and integrally united at the ends to each other andto the journal boxes, the intermediate portions of said compression andtension members being spaced by bolster guide columns or strut portions,not shown. Inasmuch as certain of the aforementioned features are usualand well known and are not part of my invention, they are notillustrated.

- in the present embodiment of my invention the compression and tensionmembers are respectively inverted U and ii-shaped in cross section, saidcompression member being formed withv an upper web 5 and dependingflanges 6 preferably beaded, as indicated 7, along their lower edges.The tension H1633" v compression member if desirably discontinued shortof any union with the journal box to effect a saving in weight andfacilitate core removal.

The journalbox is not only connected. to

I the frame by having the flanges of the members, after mergence,integrally united to the roof thereof but the web 8 of the tensionmember is united directly with the roof of the box along the inner edgethereof or upper edge of the adjacent side wall and.

more specifically preferably in line with the inner brass lug 13 of saidbox. Adjacent the union with the roof of the box the web of said tensionmember is preferably slightly thickened, as indicated at 14. Thestrength of connection with said box is desirably additionallyreinforced by providing outstanding gussets 15 preferably formed asflared gxtensions from the web of the tension mem- For additionallyreinforcing the connection with the journal box a longitudinallyextending rib 16 is preferably provided along the longitudinal centerline of the tension member web 8 and frame, said rib preferably being ofgreater strength directly over the junction between the box and web ofthe tension member and tapering both ways from said junction so as togradually merge into the web of the tension member at one end and into atransverse reinforcing web 17 extending upwardly from the roof of thebox 4 between the side walls of the frame and preferably tapering fromeach side Wall to the union with the rib 16. -The upper edge of said ribis preferably beaded along its intermediate. portion, as indicated at18, giving said rib a T-shape in cross sec- I tion. Said beadingpreferably tapers both ways from a point nearest the junction betweenthe tension member and box so that the ends of the rib 16 are free fromthe beading 18. This construction provides for maximum economy in theuse of the reinforcing" metal. For further strengthening the connectionbetween the box 4 and the frame, the inner side wall 19 of said box ispreferably directly united to the undersurface of the tension member ,3by a strut or tie member 20, the upper edge of which is preferablyspaced from the corner between the web of the tension member and the boxand both edges are preferably beadedor flanged, as

indicated at 21, for improving the strength of said member.

Referring now to the embodiment of my invention illustrated in Figures 4and 5, a construction is there disclosed involving a frame 1 having thetension member 3, the compression member 2, and the integral journal box4 at each end thereof. As in the 11 of the inner side wall 19 of the boxis 8' b a gusset 20*, the lower edge of which is pre erably beaded, asindicated at 21, which gusset entirely closes the angle beneath the webof the tension member and inwardly of the inner side wall of the journalbox. Except as specifically described in connection with the presentembodiment, the construction thereof may correspond with that of thefirst embodiment.

Referring now to the embodiment of my invention illustrated in Figure 6,a construction is there disclosed which may be identical with theembodiment illustrated in. Figures 4 and 5 except that the web of thetension-member and the roof 11 of the journal box 4" are provided with aplurality of reinforcing ribs 16 which extend over the junctionbetweenthe-web of the tension member and the roof of the journal box and taperboth ways therefrom. As in the revious embodiment, the ribs 16 mer einto the transverse reinforcing web 17 etween the sides of the framealong the transverse center line of the box. Otherwise the constructionof the present embodiment may correspond with that of the previousembodiment.

From the foregoing description it will be appreciated that I haveprovided means for heretofore became evident by the development ofcracks at such points when frames unprovided with my reinforcements weretested.
